VyOS Helium (1.1.7) spontaneous reboot


#1

Hi Guys,
We a Dell Power Edge 1950 running VyOS 1.1.7, 16Gbps of RAM and Processor Intel Xeon E5450:

amascarenhas@goc-spo1-rtr-01:~$ sh version

amascarenhas@goc-spo1-rtr-01:~$ show system memory

We note that the router is rebooted always in the same hour (1:58 am) in sporadic days.

We’d like a help to understand why this occurs. We deactivate the flow exporting to mitigate the issue, but We’d like to track it.

We check schedulers, crons and etc… but We didn’t find anything.

Could you help us?

Regards,
André Mascarenhas

And your system log when your VM reboot,…
Do you think it’s about a snapshot during a backup for example ?

Hi Friend, It seems not.

I’ve searched in many directories for the correspondent logs but didn’t find anything.

We note that after shutdown the Netflow process the We didn’t have any issue.

About the snapshot, I’m asking to the Xen Server manager ok.

Sorry, about the snapshot, the Server is physical! So We don’t have any policy about.
